IoT Control System for Industrial Rice Flatbed Dryer

Built solo as part of a DOST-funded startup incubation program affiliated with Ateneo de Naga University. Designed a complete control system for a 6-ton industrial rice flatbed dryer: a custom PCB (PLC-style, built to minimize industrial electrical noise), ESP32 firmware, motor and contactor interfacing, and all electrical wiring. Paired it with a web-based interface secured by a custom JWT handshake between the microcontroller and the site.

Field Logistics Process Improvement — Lean Six Sigma / DMAIC

Define — projects were flowing continuously, but profitability wasn't improving proportionally.
Measure — reviewed cash flow, bidding win rate, turnover times, and payment collection timelines.
Analyze — root cause: workers were making costly repeat or extended trips to remote sites due to incomplete pre-departure planning.
Improve — introduced a mandatory pre-travel checklist and a pre-dispatch planning meeting between the project engineer and lead foreman.
Control — both remain in active use today.
